About a year and a half ago, we covered a cooperative board game called Castle Ravenloft. That game was the first in a series using rules known as the Dungeons & Dragons Adventure System. This system allows all players to play together as a team, with no Dungeon Master required. Castle Ravenloft was quite good, as was the follow-up, Wrath of Ashardalon. The third (and perhaps last) game in the series, The Legend of Drizzt, is the topic for Tabletop Co-Op today.
